Abstract

A fluid control system for master-slave power steering combinations includes master and slave steering units, a pump, a low pressure discharge line from the master unit, a low pressure transfer space in the slave unit and a low pressure return line to the pump. The transfer space receives heated, low pressure exhaust fluid through the discharge line from the exhaust chamber or space of the master unit. The fluid return line is connected to the transfer space of the slave unit to feed the intake side of the pump. Build-up of pressure in the slave unit is prevented. Secondly, the fluid circulated through the transfer space of the slave unit transfers heat generated in the pump and the master unit. The temperature gradient between the master and slave unit is thereby minimized to effect cooling or heating in the system, as needed. Further, build-up or accumulation of air bubbles in the slave unit is alleviated. The steering units are preferably integral steering gears with the discharge means of the master unit and the transfer space of the slave unit including the space that encloses the output pinion. Single fluid transfer hoses interconnect the power chambers of the steering units. The piston of the slave unit is hollow with plugs closing the ends.
